Adicionar Relatório de Cobertura de Código ao Projeto Laravel

Insira este código no arquivo “phpunit.xml” na raiz do seu projeto.

<logging>
    <log type="coverage-html" target="./report" charset="UTF-8"
        yui="true" highlight="true"
        lowUpperBound="50" highLowerBound="80" />
</logging>

e este é um resultado final:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="bootstrap/autoload.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false"
         syntaxCheck="true"

    <testsuites>
        <testsuite name="Application Test Suite">
            <directory>./app/tests/</directory>
        </testsuite>
    </testsuites>
    <filter>
        <blacklist>
            <directory suffix=".php">./vendor</directory>
        </blacklist>
    </filter>
    <logging>
        <log type="coverage-html" target="./report" charset="UTF-8"
            yui="true" highlight="true"
            lowUpperBound="50" highLowerBound="80" />
    </logging>
</phpunit>
